In order to verify the "radiation protection" effect of prosthetic groups in irradiated conjugated proteins and the influence of their electronic structure on intramolecular excitation transfer, two series of substances were examined. The first was composed of ferrihemoglobin and its constituents and the second was composed of similar hemoproteins with heme groups with major differences in electronic structure. The results point to a strong radiation protection effect of the heme groups and a dependence of radical yield of hemoproteins on the electronic structure of the heme. A possible interpretation of this latter effect is discussed.
为了验证辐照共轭蛋白中辅基的“辐射防护”作用及其电子结构对分子内激发转移的影响，对两个系列的物质进行了研究。第一个系列由高铁血红蛋白及其成分组成，第二个系列由具有电子结构存在重大差异的血红素基团的类似血红蛋白组成。结果表明血红素基团具有很强的辐射防护作用，并且血红蛋白的自由基产率取决于血红素的电子结构。文中讨论了后一种效应的可能解释。
